Bummer ;-)
I don't think I have a developed an application in the last 10 years that hasn't has to do this. I was quite surprised when I discovered this feature was missing in formish, but it seems to be missing in quite a few other form libs like wtforms as well. I suppose at least they all have declarative method of defining the schema, but it does mean the actual schema definition is a bit more obscured.
